Yes, the 3D HDTV has been coming! Samsung has released 3D HDTV and now is available at Amazon.com. You can choose models with 46-inch or 55-inch screen, LED or plasma technologies.

There are two models of the Samsung 3D LED HDTV (7000 series): Samsung UN46C7000 and UN55C7000 with screen size of 46-inch and 55-inch respectively. They have the same features except their audio power. The UN46C7000 sports 10 watts x2 audio power stereo , while the UN55C7000 is more powerful 2x15 watts.

The both models are not only 3D ready, but they can also be used for accessing Internet. They need wired or wireless (Wi-Fi) network for connecting to the Web. Once connected to the Intenet, you just select one of many widgets for accessing Facebook, YouTube, Twitter, Flickr, eBay, RallyCast, Yahoo! Weather/News, or USA Today Sports.


You can also connect a PC to the HDTVs for streaming video or audio and display pictures. A digital camera, USB drive, or video cam can be connected directly for sharing videos and photos with your family.

There are also game applications ready to play, such as Monopoly from EA, interactive card games, and more.

Samsung 7000 series are more than 3D LED HDTV.

Samsung 3D glasses for its 3D LED, LCD, and plasma TVs cannot be used with other TV brands. The electronic shutter 3D glasses will come in three versions: One powered by an internal rechargeable battery (US$200), another with a replaceable coin-sized battery (US$150), and a smaller set of rechargeable glasses for children (US$180).

The model with battery offers about 400 hours of use between batteries, while the rechargeable units should be charged fully before watching an average-length movie.

The same Samsung 3D glasses will provide an identical 3D viewing experience whether they are used to watch movie on LCD and LED panels or plasma screens. Samsung’s representative explained that plasma screens do not refresh image the same way as LCD and LED panels. Samsung’s LED and LCD Tvs provide a 240Hz refresh rate, the glasses refresh at half that rate (120Hz) because they synchronize to 3D content by alternately closing and opening each side.

Some vendors have announced their 3D TV products. They will ship them in the next couple months. Samsung has began producing 3D-compatible LED and LCD screens. On the other hand, LG will launch 3D TV series in April 2010.
